1 ABSTRACT High and growing rates of unemployment have been a source of great frustration to policy-makers. Although exports have been buoyant and the 1990s has been the first decade of sustained growth, unemployment has been rising by 2 percentage points each year. If the expanded definition is used, the rate of unemployment reached 41.8% in September 2002. In a context where the majority of t...

To model Web services handling data from an infinite domain, or with multiple sessions, we introduce fresh-variable automata, a simple extension of finite-state automata in which some transitions are labeled with variables that can be refreshed in some specified states. We prove several closure properties for this class of automata and study their decision problems. We then introduce a notion o...

In this paper we focus on a hardware realization of web services (WS) and their integration within the service-oriented architecture (SOA). Previous approaches to the implementation of network-enabled services in hardware covered only very specific types of applications and were platform-dependent. Our contribution is a generic framework where heterogeneous everyday objects are enhanced with ap...

With the development of the Internet, Web services, such as Google Maps API and YouTube Data API, become more important and convenient for the Web knowledge distribution and integration. However, currently, most existing Web sites do not provide Web services. In this paper, we present a partial information extraction technology to construct the Web services from the general Web applications qui...

The issue of cloud computing is a highly topical issue. Cloud computing represents a new model for information technology (IT) services based on the exploitation of Web (it represents a cloud) and other application platforms, as well as software as a service. In general, the exploitation of cloud computing in construction project management has several advantages, as demonstrated by several res...

The UK construction industry at its best is excellent. Nonetheless there is a deep concern that the industry as a whole is underachieving. Problems such as low and unreliable profitability, a lack of research and development, a shortage of skills, usage of tender price evaluations, and a fragmented industry structure, are widely recognised by the industry. These problems must be tackled in orde...

Résumé Les architectures orientées services (AOS) se sont imposées pour la construction d’applications web grâce à l’élaboration de standards ouverts et compatibles avec les technologies web existantes. Le nombre de services sur le web grandit chaque jour et les développeurs d’applications sont souvent confrontés au problème de choisir parmi les services disponibles. Cet article présente un mod...

In this paper, we present our approach in the field of e-Government services construction. In this work, the ontological level extracted from legal sources is used as means to define and to construct e-Government services. Building Information System (IS) and e-Government services based on legal sources presents many advantages: (i) the services and IS conforms to the legal framework that organ...
